Analysis of the effect of graphene oxide on polymer electrolytes based on PVDF for lithium‐ion battery

Polymer electrolytes have been studied for structural flexibility, non-settling, and increased safety in lithium-ion batteries. Polyvinylidene fluoride (PVDF) is a semi-crystalline polymer, a good candidate for making polymer electrolytes due to its desirable properties. However, polymer electrolytes have low ionic conductivity. In this research, graphene oxide enhancer (GO) additive has been investigated to solve the problem of low ionic conductivity and improve ionic conductivity. The nanoparticles are optimized using morphology, tensile strength, ionic conductivity, lithium transfer number, and electrochemical stability. The microscopic images obtained in this electron experiment show a more porous structure of the electrolytes containing nanosheets than the pure electrolytes. The results show that the addition of GO increases ionic conductivity and also improves the physical properties of the polymer membrane.
